Prior to actual power up and initialization, check out the STSe System to avoid start up delays
or improper loading. A step-by-step checklist is provided for this purpose.

Preliminary Procedures

1. Make sure the Basic Key Service Unit (BKSU) is properly grounded to a cold water pipe or
earth ground.
2. Verify that all expander modules are firmly seated onto their connectors.
3. Inspect the Main Distribution Frame (MDF) for shorted wiring and improper polarity that
would affect the Digital Terminal or DSS console.
4. Make certain the lithium battery switch (SW4) on the Main Board Unit of the BKSU is set
to the ON position to enable the battery backup option.
5. Make sure the MDF cables connected to the BKSU are secure and plugged into the
correct position.

Power Up Sequence

The power up sequence involves 1) the proper application of AC power to the system and
2) defaulting the system. A successful power up is assured if installation checklist is followed.
1. Plug the AC power cord of the Key Service Unit into the dedicated 117V AC outlet.
2. Turn the power switch of the KSU to ON.
3. On the MBU, set switch 8 on(SW5) to the OFF position to retain changes to the database.
The system is ready for programming. If problems occur, refer to
and Troubleshooting."
